Écrainville (French pronunciation: [ekʁɛ̃vil]) is a commune in the Seine-Maritime department in the Normandy region in northern France.

A farming commune made up of 11 villages and hamlets in the Pays de Caux, situated some 13 miles (21 km) northeast of Le Havre, at the junction of the D68 and D139 roads.

The first written mention of Écrainville or one of its hamlets dates back in the late 11th century.

In 1180, the lord of Tennemare or Tannemare appeared in the records of the Exchequer of Normandy.

Until the 17th century, the seigneurie passed from father to son of the Folville family.
